The word that ends every prayer is "amen." And it has a simple meaning. This word dates back to the time of the first written words and appears in the earliest Jewish texts.
Amen is a word derived from the Hebrew word āmēn. This word,
spoken at the end of each prayer, is one of the few that has remained almost
unchanged since its inception.
It has survived for thousands of years, and its form has
only been adapted to several different languages, while its meaning has
remained the same.
This word dates back to the time of the first written words
and appears in the earliest Jewish texts. Its meaning is associated with
approval and signifies something that is yet to happen.
The translation of the word amen is "so be it!", "So it is!"
Amen is also used to indicate strong agreement with
something and in that sense means "truly, without doubt,
indisputably." Etymologically, this word comes from the Hebrew verb
"aman," which translates as "strengthen, confirm." However,
the root of this word is Semitic and can also be found in the Aramaic language
spoken and preached by Jesus Christ himself.
In Orthodox Gospels, this word is used 77 times, mostly
attributed to the Savior.
Grammarians consider the consonantal root of this word to be
"amn" (because "alef" functions as a consonant in Hebrew
morphology) and that this root means "to be firm, confirm, reliably,
faithfully, have faith, believe."
Even Arabs have the word "amana," which has the
same meaning and transforms into "amin" in the same way as in Hebrew.
Muslims use the word "amin" just like Jews and Christians: when they end prayers.
Many proponents of theosophy, Afrocentric historical
theories, and esoteric Christianity believe that the word "amen" is
connected to the Egyptian god Amun, sometimes called Amen. At one point, Amun
merged with the sun god Ra to become Amun-Ra; in that form, he was the king of
gods and the most important Egyptian deity, transcendental, self-created, and
unparalleled, the protector of the poor, and the central being concerning
personal devotion.
It has gone so far that the Egyptian religion at one point
became practically monotheistic because all other gods were treated as
manifestations of Amun.
